What is a mergers and acquisitions (M&A) API?

An M&A API returns deal events (the acquirer, target, deal value, and stake) as structured data you can query and pipe into your own tools. The Signalbase M&A API detects the announcement as it happens and ties both companies to verified profiles, so you get the timing, not just the record.

How fast does Signalbase detect a deal?

Deals are pushed on a flow, not a scheduled refresh. Typical lag from public announcement to the event landing in your endpoint is under a minute, against the monthly cycle most deal databases run on. That figure is a floor for cleanly resolvable companies, not a guarantee across every deal.

Can I filter deals by type, value, or region?

Yes. Deal type, value range, stake, country or region, and detection timestamp are all query parameters. Narrow the flow to your ICP before it reaches your CRM, with no post-processing on your side.

Does the M&A API cover every deal?

No, and we would rather say so. Coverage is strongest where the deal is public and both company names resolve cleanly. Undisclosed deals, generically named entities, and thinly reported regions are where it drops off. If you need to catch deals early, this is built for that.

How do I start using the M&A API?

Start a 7-day trial, pull your first events in a few lines, and test against real data. Full endpoints and parameters are in the documentation.

Oxygen

Stock vs flow

Databases log deals on a schedule. We catch the announcement live.

A live M&A stream tells you an account just changed hands, with a new owner, a new budget, and integration work ahead, before the deal shows up in anyone's monthly refresh. That window is where the displacement plays are.

Benchmark

Most tools log the deal weeks later. We verify and contextualize it live.

Every other tool hands you a deal record long after the window opened. The M&A API detects the announcement itself and hands you the acquirer, the target, and the source.

Delivery

Three ways to push the data to you.

The same deal events, delivered where you work: pull them on your schedule, have them pushed the moment they land, or wire them natively into your agents.

Pull

REST API

Poll the endpoint with a since cursor on your own schedule.

Push

Webhooks

We post the event to your endpoint the moment it lands. This is the flow, not a nightly batch.

Native

MCP

Wire the same signals straight into your agent or GTM tooling over the Signalbase MCP.

Built for

Where teams point this API.

Displacement plays

Reach the acquired account while integration is in flux and the incumbent contract is suddenly in question.

Account scoring

Feed live deals into your model so a change of ownership lifts the accounts with fresh budget and new priorities.

Territory alerts

Route each announced deal to the rep who owns the account the same day it breaks, straight into your CRM.

Building internal AI SDRs

Find your ICP once and let deal signals populate while you never touch the UX again.

We have tried other financial signals providers, such as Crunchbase. Despite being more expensive, they could not match Signalbase's timeliness or the ability to trace data back to source posts.

We have been searching for a signal infrastructure for months and happily ended up with Signalbase. The data is top tier and the platform and API are very straightforward.
